Explain where in the citric acid cycle a hypothetical defect of an enzyme could occur that prevents an increase in adenosine triphosphate (ATP)

Explain where in the citric acid cycle a hypothetical defect of an enzyme could occur that prevents an increase in adenosine triphosphate (ATP) production in response to an increased energy need and how the products of the citric acid cycle are converted into ATP.
